Is Carbon Hydrogen Bond Polar
On the polarity of the carbon-hydrogen bond
The carbon-hydrogen bond is the key to chemistry. To understand its polarity, we should investigate its essence.
Carbon, one of the chemical elements, has a stable nature. Hydrogen, also an element, is light and alive. When the two meet, they form a carbon-hydrogen bond.
Looking at its electronegativity, carbon has moderate electronegativity, and hydrogen has slightly less electronegativity. Electronegativity, the ability of atoms to attract electrons in molecules. Because carbon is more electronegative than hydrogen, when bonding, the electron cloud is slightly biased towards carbon. The offset of this electron cloud causes the carbon end to be slightly negative and the hydrogen end to be slightly positive. From this perspective, the carbon-hydrogen bond is actually polar.
However, the degree of polarity is different from that of other polar bonds, such as hydrogen-oxygen bonds. In hydrogen-oxygen bonds, the electronegativity of oxygen is much stronger than that of hydrogen, and the electron cloud shift is significant and the polarity is very strong. Although the carbon-hydrogen bond has an electron cloud shift, the degree is slightly weaker.
In summary, the polarity of the carbon-hydrogen bond does exist, but its polarity is strong or weak, when compared with other bonds. This is the gist of exploring the polarity of the carbon-hydrogen bond.
